THOMAS GRAVES, OF MEMPHIS, TENNESSEE..

EGG TESTER.

Application led October 7, 1921. Serial No. 505,Q49.

To all whom it may concern.:

Be it known that l, THOMAS GRAVES, a citizen of the United States, residing at Memphis,`in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Egg rlesters, of which the following is a specification.

The present invention relates to egg testers and has for its principal object to generally improve upon devices of this nature by pro viding a simple and efcient structure which will be durable and inexpensive, one which is eilicient and reliable in operation and well adapted to the purpose for which it is dev signed.

Another important object of the invention is to provide an egg tester capable of being readily opened so that easy access may be had to all parts thereof.

Another object of the invention is to provide an egg tester having an illumination compartment and a dark compartment with structure for supporting an egg therebe tween so that it may be tested to advantage.

With the above and numerous other important objects in view which will appear as the description progresses, this invention consists of certain novel features of construction, and the combination and arrangement of parts as lwill be hereinafter more fully described and claimed.

ln the drawing Figure 1 is a perspective of the egg tester,

Figure 2 is a longitudinal vertical section therethrough,

Figure 3 is a transverse vertical section therethrough,

Figure 4 is a horizontal section through the lower compartment thereof showing the same when batteries are used, and

Figure 5 is a similar view showing the same when the electric current is furnished from outside the egg tester.

Referring to the drawing in detail it will be seen that 1 designates the base of the egg tester which has hingedly mounted thereon. adjacent its longitudinal side edges the base side panels 2. Each side panel 2 is provided with end plates 3 at its transverse edge so that when the panels are situated at right angles to the base 1 these plates 3 form end panels for the lower box-like structure. Hooks and eyes 4 are used for holding the plates 3 together. The opening 5 is formed from notches in the plates 3 registering with each other sothat an electric wire as shown in Figure 5 may be passed therethrough and attached to an electric bulb 6 for the purpose of illumination. A switch 7k in one of the base sidepanels 2 ris interposed between the source of electrical energy and the electric bulb 6. lnFigure 4 it islshown that dry cells 8 may/.befuse'd asia source of electrical energy if so desired and this latter form is preferable. The top plates 9 are fixed to the upper longitudinal edges of the panels 2 so as to extend at right angles thereto and form a top panel for the lower or illumination compartment which will preferably be painted white. Registered notches are also provided in the top plates 9 so as to form an opening for supporting the egg 10 and this opening is preferably lined as indicated at 11. lt is, of course, to be understood that as many of these openings may be provided as may be found desirable. The upper or darkened compartment is formed by the upper side panels 12 and 13 which are hinged at 14 to the top plates 9. The upper side panel 12 is provided with the end panels 18 and cover panel 14. The cover panel 14 is held in engagement with the panel 13 by the hasp 15 which may be of any preferred construction. A n opening 16 is provided in the cover panel 14 so as to be in registry with the egg receiving opening and a magnifying lens 17 is preferably placed therein.

It is thought that the construction and operation of the egg tester will now be understood without a more extended explanation. As numerous changes in form, and in the combination and arrangement of parts may be made without departing from thespirit of this invention, l do not wish to be limited to the construction herein shown except as hereinafter claimed.

Having thus described my invention what l claim as new is 1. An egg tester of the class described comprising an illuminated compartment including a base panel, a pair of side panels, one side panel hinged to each longitudinal side edge of the base panel, four endplates one fixed perpendicularly at each end of each side panel so as to form end panels for the compartment, a pair of top plates one fixed perpendicularly to the free longitudinal edge of each side panel to form a top panel, said top panel provided with an opening; and a darkened compartment including side panels hinged vto the top plates of the illuminated compartment, end .panels 'iiXed to one side panel of the darkened Compartment and a hinged cover panel provided With an opening and engaged on one side panel of the darkened compartment.

2. An egg tester of the class described comprising an illuminated compartment including a base panel, a pair of side panels, one side vpanelhinged Ito eeach longitudinal side edge of the base panel, four endp'lates one iiXed perpendieularly atA each end .of each side panel so as to-form end panels for the compartment, means Vtor holding adjaeent end plates together, a pair of top plates, one fixed perpendioularly' to the 'free' longitudinal edge of each side panel to form a kto the top plate of the illuminated compartment, end panels fixed to one of the side panels of the darkened compartment, and a hinged cover panel on one side panel ofthe darkened compartment and provided With an opening registering With the egg receiving opening in lthe vtop panel .of Athe :illumi- `n ated l compartment.
